Whipple City Festival - Held annually in the center of the village, a week-end long event normally held in the middle of June. Truly a local favorite.
Harvest Festival - A fairly new tradition to commemorate the yearly harvest.
Washington County Fair - Just on the outskirts of the Village on the Washington County Fairgrounds, held every year is the Washington County Fair. Residents of Greenwich and neighboring Easton have enjoyed this yearly event for close to a century.
